Picked Cho and goes into the game... then crashes

The games before played well and moving on to the next game with cho-gath I couldn't enter the game after champ select. I lost my team the game and I got demoted cause of it! I kept attempting to reconnect to the game but that didn't work at all. the game kept crashing and now I am going to pick a different champ to see if Cho was the problem... Going into the game I picked Udyr and the game loads just fine... I think Cho-gath is bugged /: ahhhhh
